The 21-year-old midfielder has been one of the standout performers for the newly-promoted team, who have won praise for their stylish football.

His form has caught the eye of Tottenham boss Harry Redknapp , who is now considering making a bid, reports the People.

The Wales international is the kind of clever midfield player Redknapp likes and he would add a further creative option to Spurs’ title-chasing squad.

Swansea manager Brendan Rodgers would not want to lose Allen at this stage of the season and would demand a fee in excess of £10million for a player who is under contract until 2015.

Redknapp has been told there are funds available for transfers this month and Spurs could afford the deal without having to sell Luka Modric, who has again been linked with a move to Manchester United in recent days.

Tottenham are, however, looking to offload Giovani dos Santos and Vedran Corluka before the January transfer window closes.

Giovani is a £5million target for Bolton Wanderers, while Roma are rumoured to be keen to take Corluka on loan.
